Hi,
Your HTTPS Certificate for https://docs.myriadrf.org/ expired today.
Also, I’ve noticed that the docs hosted online are an older version than the ones in the github doxygen section.
We’re going to take down that old docs instance and it will be replaced with better documentation, still with Doxygen generated docs, and with a process to ensure it gets updated with each release. This is a work in progress and for now would suggest building the docs locally.
